Product Description

This NBN brake master cylinder is designed specifically for Audi vehicles, ensuring precise hydraulic control for your braking system. As a crucial component in the brake and clutch assembly, the master cylinder converts pedal pressure into hydraulic force, enabling effective braking performance. Constructed with an aluminium body and machined finish, it features dual reservoir ports and a secure piston rod, supporting reliable operation under various driving conditions.

Compatible with selected Audi models, including A4 (B8), A5, A8, and Q5 with engine sizes ranging from 1.8 to 6.3 FSI, TFSI, and TDI from 2007 to 2018. Always confirm your vehicle’s model, year, engine size, and engine code before ordering to ensure the correct fit.

A failing brake master cylinder can lead to a range of braking issues. Symptoms may include a spongy or sinking brake pedal, reduced braking efficiency, difficulty maintaining brake pressure, and visible brake fluid leaks near the cylinder or pedal area.

Replace the brake master cylinder if you notice any of these symptoms or during major brake system overhauls. Prompt replacement helps maintain safe stopping distances and prevents further damage to other braking components.

Installation note

Frequently Asked Questions

What are the signs of worn brake pads or brake components?

Common signs may include squealing or grinding noises when braking, reduced stopping ability, a soft brake pedal, vibration under braking, or the brake warning light on your dashboard. Because brakes are safety-critical, diagnosis and inspection by a qualified mechanic is recommended before replacement.

Can I replace only one side of the brakes?

Brake pads and discs are normally replaced as an axle set (both sides at the same time) to maintain balanced, even braking. Replacing only one side can cause the vehicle to pull when braking. Consult a qualified mechanic for guidance.
